Hey fella's maybe you can give me some insight on this before i go into my "trial and error" carb tuning session.
Ive added a Two Brothers M7 slip-on to my KX450F. The exhaust apparently is more "high flow" than the oem supplied muffler.
In riding the machine thus far it appears to have a little more punch in the mid to upper end compared to the oem pipe.
My concern and question centers around the drastic increase in decel pop with the new pipe.
Ive made adjustments to my pilot air mixture screw and it lessened the "snap" some.
I do understand a degree of decel snap or pop is common and to be expected, but the machine does it quite a lot and from all indications too much. The machine also feels as if the mid rang punch comes on ....leading me to believe the bike needs some adjustment down low.
How are you guys compensating for slip-on exhausts on your 450 4 strokes?
Just mixture screw?
Larger or smaller (i assume larger) pilot jet?
Needle adjustment??
Im leaning toward mixture screw and a larger pilot jet.
Any input is appreciated.
